N2 - A series of sorbents were prepared, and their performance on removal of phenol from wastewater was investigated in this study. It indicated that the suitable compositions for the prepared sorbent mainly consisted of 0.5 wt.% PtO, 4.5 wt.% MnO, 1.99 wt.% Fe2O3, and 2.4 wt.% CoO, respectively, and supported on Al2O3, shortened as an APMFC1.2 sorbent, A, P, M, F, C indicated Al2O 3, PtO, MnO, Fe2O2, CoO, respectively, and number 1.2 as the molar ratio of Co. Studies showed that the spent sorbent could be effectively regenerated at 240°C by gas mixtures of 6.0 mol.% steam balanced with air. Multiadsorption-regeneration cycles conducted on APMFC 1.2 sorbent indicated that it had good regenerability at the experimental conditions, and characterized results further confirmed that the APMFC1.2 sorbent had stable structure, which implied APMFC 1.2 sorbent could be a promising sorbent/catalyst to be used in the process of removal of organic compounds in wastewater by adsorption combined with catalytic oxidation methods.
